You should really be asking this on the RFI list, but I'll take a stab at it.

I use my Kenwood TH-F6A when I need to do some RFI snooping. It has a built-in 
loopstick antenna that works fairly well on HF. The receiver is not very 
sensitive, but if you 
are close to a really loud source you will hear it. AND -- a major mechanism by 
which this 
stuff radiates into our antennas is via the vertical downlead from capacitors 
and protection 
devices at the top of poles. These downleads are not present on all poles, but 
they are on 
many of them. The Kenwood hears this stuff real well -- just put it near the 
downlead! Other 
similar radios should do this trick too. 

Obviously we could get much fancier, but I always begin by looking in my 
existing box of 
tools before buying something.
